Here's the pics... I've got 2 of the bookshelf speakers and theyre 6ohm each. Im just wondering if it would be worth using one of these receivers (i like the onkyo) in my dorm opposed to the Logitec z-2300 2.1 setup i was gonna use.

How much power do u think the either of the 2 big receivers would put out bridging 2 outputs to a sub and running the other 2 to the kenwood bookshelfs?
